PHOTONIC CRYSTAL BASED OPTICAL DOPPLER PROJECTILE DETECTION SYSTEM

摘要

A method for use in sensing a moving object by doppler global sensing includes illuminating the object with energy, filtering energy reflected by the object with a frequency selective surface filter, and sensing the filtered energy. An associated system includes a laser operable to illuminate an object with energy and a frequency selective surface operable to filter energy reflected off the object. The system also includes a camera operable to receive energy reflected off the object that is passed by the frequency selective surface.
